USING HE'AVY OIL IN GAS MAKING.

Specification of Letters Patent.

Patented June 6, 1922.

Application filed July 2, 1920. Serial No. 898,663.

To all whom it may concern:

Be it known that' we, OWEN B. EVANS and HARUTYUN G. TERZIAN, both citizens of the United States, residing at Philadel hia, in the county of Philadelphia and I tate of Pennsylvania, have jointly invented certain new and useful Improvements in Using Heavy Oil in Gas Making, of which the following is a specification.

The principal object of the present invention is to provide for the successful use, in the manufacture of carbureted water gas and oil gas, of heavy oil, meaning oil such as has a coke content sufficient to stop up or clog the checker-brick upon which it is sprayed or otherwise introduced by forming a deposit of carbon or coke thereon or therein.

In the practice of this invention the comparatively cool coke or carbon deposit on or at the entrance to the checker-brick is consumed or burned and removed by back blasting the apparatus with air which before reaching the comparatively cool deposit and in back traversing the checker-brick is sufficiently heated to burn the carbon or coke deposit.

Accordingly the invention comprises the process of back blasting for the purpose indicated, as well as the rocess to be presently described and ,finall cIaimed.

In further descri ing the invention reference will be made to the apparatus shown principally in elevation, but with parts broken away, on the accompanying drawings and which is an ordinary carbureted water gas set and was chosen for convenience only.

The introduction of oil onto or at the en trance 1, of the checkerbrick, in the carbureter 3, occurs during the run and after, the,

Such a carbon deposit interferes with and even prevents the normal practice of'the as making process. We remove this carbon eposit or coke from the entrance of the checkerbrick 1, by backblasting the apparatus in the direction of from the fixing chamber stack 5, towards the nerator 4. By this back blasting the air is heated in traversing comparatively hot portions of the cheokerbrick and ignites and consumes the comparatively cool carbon deposit or doke at the entrance of the checkerbrick. The back blasting can be done from any of the air blast inlets 7, 8 or 9, and the roducts of combustion of the coke or car on deposit can be led oil" by Way of the generator fuel inlet 11, or by way of a stack 12, rovided on the carbureter for the purpose. he back blasting can be done while the gas making process is suspended for the urpose of cleanmg the fire, and regular or orward blastin as from the blast inlets 10 and 13, can be al ternated with the back blasting to temper the heating of the checkerbrick. Any of the coke or deposit which may reach the bottom of the carbureter 3, may be removed throu h the cleaning door 14.. By spraying t e heavy oil as from 15, in a number of comparatively large streams, the deposit occurs on the checkerbrick inseparated spots, so that the back blast by passing between the spots has good access to the coke or deposit for burning it ofi, and this is true in case the blast is introduced at 10, andled oil at 5, which is ossible when the carbon deposit at the top othe carbureter happens to be, at the time, hot.

The wider the spaces between the bricks the longer it will take for the deposit from the oil to choke the checkerbricl'r; so that it is well to space the bricks quite wide apart and in this way assure a passage for the back blast.

From the foregoing description of one application of the invention in connection with the described apparatus it will be obvious that in one of its aspects the invention consists in providing for the use of heavy oil by permitting it to deposit carbon on the checkerbrick and then consuming the deposit by blasting it with previously heated air.

We claim:

1. The process of using heavy oil in the manufacture of gas which consists in gasifying heavy oil by introducing it onto preheated checkerbrick thereby forming a carbon de osit on the checkerbrick, and consuming said deposit by back blasting the checkerbrick with air which is heated by the checkerbrick before reaching the deposit. substantially as described.

2. The process of using heavy oil in the manufacture of gas which consists in gasify ing heavy oil by introducing it'onto checkerbrick pro-heated by forward blasting, back blasting the checkerbrick to consume the carbon deposit from the oil, and alternately back and forward blasting to temper the heat, of the checkerbi'ick, substantially as described.

3. The process of using heavy oil in the manufacture of gas which consists in gasify- 15 ing heavy oil by introducing it in spots onto the preheated checkerbrick thereby forming spaced carbon deposits on the 'checkerbrick, and consuming said deposits by back blasting the checkerbrick with air which is heated by, the checkerbrick before reaching the deposit, substantially. as described.

4. The process of using heavy oil in the manufacture of gas which consists in 'asifying heavy oil by introducing it to pre eated checkerbrick thereby forming a carbon deposit on the checkerbrick, and consuming said deposit by blasting it with previously heated air.
